下面是埃氏素数筛的Python实现，横线上应填入的代码是（ ）。

def listPrime(N):
    primeList = list(range(N+1))
    primeList[0] = primeList[1] = False
    for i in range(2,int(N ** 0.5) + 1):
        if primeList[i] != False:
            for j in range(_____________):
                primeList[j] = False
    return [x for x in primeList if x != False]
